The Purchase dependent variable will require wrangling to work in logistic regression. We replaced it with a purchase_mm logical variable. Wrangle other categorical variables to be factors too.

juice <- juice %>% mutate(purchase_mm = if_else(purchase == "MM", 1, 0),
                 .after = purchase)
juice <- juice %>% mutate(
  store_id = as.factor(store_id),
  store = as.factor(store)
  #weekof_purchase = as.factor(weekof_purchase)
)

#what's so special about store 7? 
#store and store ID ? 

WeekOfPurchase is also quite tough to deal with: should it be added as a factor variable (it will lead to many coefficients), left as numeric, or omitted entirely? See if you can come up with a strategy to decide what to do with it.

juice %>% select(weekof_purchase) %>% 
  distinct()

#There are a lot of weeks, I don't think the week will have a big impact 
#on people's behabiour of buying what juice. I am going to put them into 
# fewer groups just in case there are some seasonal impact. 

Check for aliased variables and remove any aliases before you set off to find your best models. Remember, you can use something like alias(purchase_mm ~ ., data = oj) to do this, the dot . here means ‘all variables’. Aliased variables will be listed down the left-hand side, and you can subsequently remove them.

alias(purchase_mm ~ ., data = juice)

Model :
purchase_mm ~ purchase + weekof_purchase + store_id + price_ch + 
    price_mm + disc_ch + disc_mm + special_ch + special_mm + 
    loyal_ch + sale_price_mm + sale_price_ch + price_diff + store7 + 
    pct_disc_mm + pct_disc_ch + list_price_diff + store
